Where did Wilson go?

I was browsing the net the other day when I came across a link to the 10 Best TV Neighbors and there he was Wilson from Home Improvement. I love that show... it brings back such great childhood memories.

From that post I found out that Wilson (Earl Hindman) had passed away in 2003 from lung cancer. I had no idea... TV lost one of its best neighbors :( May he rest in peace.
